Parsing HTML in C++ can be achieved using libraries that provide HTML parsing capabilities. One such popular library is Gumbo, developed by Google. Gumbo is an HTML5 parsing library that provides an easy-to-use API for extracting information from HTML documents.

Here's a basic example of parsing HTML using Gumbo in C++

Install Gumbo Library

Follow the installation instructions on the Gumbo GitHub repository to build and install the library.

Include Gumbo Headers in Your C++ Code:

#include 

Write HTML Parsing Code:

#include 
#include 

void parseHtml(const char* html) {
    GumboOutput* output = gumbo_parse(html);
    // Process the parsed HTML tree
    // ...

    // Clean up
    gumbo_destroy_output(&kGumboDefaultOptions, output);
}

int main() {
    const char* html = "
Hello, World!
";
    parseHtml(html);

    return 0;
}

The parseHtml function takes an HTML string as input, uses Gumbo to parse it, and then you can traverse the resulting parse tree to extract information.

Traverse the Parse Tree:

void traverseNode(GumboNode* node) {
    if (node->type == GUMBO_NODE_ELEMENT) {
        // Handle element node
        GumboElement* element = &node->v.element;
        // Extract tag name: element->tag
        // Process attributes: element->attributes
    } else if (node->type == GUMBO_NODE_TEXT) {
        // Handle text node
        GumboText* text = &node->v.text;
        // Extract text content: text->text
    }

    // Recursively traverse child nodes
    if (node->type != GUMBO_NODE_TEXT && node->v.element.children.length > 0) {
        for (unsigned int i = 0; i < node->v.element.children.length; ++i) {
            traverseNode(static_cast(node->v.element.children.data[i]));
        }
    }
}

void processParsedHtml(GumboNode* root) {
    // Traverse the parsed HTML tree
    traverseNode(root);
}

Modify the traverseNode function according to your needs to extract information from HTML elements and text nodes.

Compile and Run:

Compile your C++ code with the Gumbo library linked.

Run the executable.

Remember to handle memory management properly and check for errors when using Gumbo. The example above provides a basic framework, and you may need to adapt it based on the specific HTML structure you are dealing with.

If your Selenium ChromeDriver with Python has stopped working, there could be various reasons behind it. Here are some common troubleshooting steps to identify and resolve the issue:

1. Check ChromeDriver Version:

   • Ensure that the version of ChromeDriver you are using is compatible with the version of Google Chrome installed on your machine. Download the latest ChromeDriver version from the official website if needed.

2. Update Chrome Browser:

   • Make sure your Google Chrome browser is up to date. An incompatible ChromeDriver version may not work correctly with an outdated browser.

3. Update Selenium WebDriver:

   • Ensure that you have the latest version of the Selenium WebDriver library installed. You can update it using:

pip install --upgrade selenium

• Check Chrome Browser Version:

  • Verify the version of your Google Chrome browser. You can find this information in the Chrome browser by going to "Settings -> About Chrome." Ensure that the ChromeDriver version matches this version.

• Provide ChromeDriver Path Explicitly:

  • Specify the path to ChromeDriver explicitly when creating a WebDriver instance. For example:

from selenium import webdriver

driver = webdriver.Chrome(executable_path='/path/to/chromedriver')

• • Replace '/path/to/chromedriver' with the actual path to your ChromeDriver executable.

• Check for Errors and Logs:

  • Examine any error messages or logs generated during the execution of your Selenium script. These messages can provide clues about what might be going wrong.

• Firewall/Antivirus:

  • Check if your firewall or antivirus software is blocking ChromeDriver. Temporarily disable these to test if they are causing the issue.

• Headless Mode:

  • If you are running ChromeDriver in headless mode, try running it without headless mode to see if the issue persists.

• Temporary Directory Access:

  • Ensure that the process running your Selenium script has the necessary permissions to write to the temporary directory. ChromeDriver may need to write to the system's temporary directory during execution.

• Try a Different Browser:

  • If the issue persists with Chrome, try using a different browser (e.g., Firefox) to see if the problem is specific to Chrome or if it's a more general WebDriver issue.

• Reinstall ChromeDriver:

  • Consider reinstalling ChromeDriver by downloading the latest version and replacing the existing executable.

• Check for System Updates:

  • Ensure that your operating system is up to date. Some issues may be resolved by updating the underlying system libraries.

• Check Browser Extensions:

  • Disable any browser extensions or plugins that might interfere with the WebDriver.

• • Replace '/path/to/chromedriver' with the actual path to your ChromeDriver executable.

• Check for Errors and Logs:

  • Examine any error messages or logs generated during the execution of your Selenium script. These messages can provide clues about what might be going wrong.

• Firewall/Antivirus:

  • Check if your firewall or antivirus software is blocking ChromeDriver. Temporarily disable these to test if they are causing the issue.

• Headless Mode:

  • If you are running ChromeDriver in headless mode, try running it without headless mode to see if the issue persists.

• Temporary Directory Access:

  • Ensure that the process running your Selenium script has the necessary permissions to write to the temporary directory. ChromeDriver may need to write to the system's temporary directory during execution.

• Try a Different Browser:

  • If the issue persists with Chrome, try using a different browser (e.g., Firefox) to see if the problem is specific to Chrome or if it's a more general WebDriver issue.

• Reinstall ChromeDriver:

  • Consider reinstalling ChromeDriver by downloading the latest version and replacing the existing executable.

• Check for System Updates:

  • Ensure that your operating system is up to date. Some issues may be resolved by updating the underlying system libraries.

• Check Browser Extensions:

  • Disable any browser extensions or plugins that might interfere with the WebDriver.

Installing a proxy on a router usually involves configuring the router's firmware to use a proxy server for routing Internet traffic. The process varies depending on the router model and firmware. Here's a general outline of the steps you can follow:

1. Access your router's administration interface: To do this, open a web browser and enter your router's IP address (usually 192.168.1.1 or 192.168.0.1) in the address bar.

2. Log in to your router: You will need the username and password for your router's administration interface. These credentials are usually provided in the router manual or on a sticker on the router itself.

3. Locate the proxy settings: Navigate to the appropriate section in the router's administration interface, which may be called "Proxy," "Internet," "Advanced," or something similar.

4. Configure the proxy settings: Enter the proxy server address, port number, and any necessary authentication credentials (username and password) provided by your proxy service or network administrator.

5. Save and apply changes: After configuring the proxy settings, save your changes and apply them to your router. This may require a restart of the router.

6. Update your device settings: After configuring the proxy on your router, you may not need to change the proxy settings on your devices. However, this depends on the router's firmware and configuration.

Please note that installing a proxy on a router can have security implications and may not be suitable for all users.

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.

It means that the address of such a server changes periodically. This is useful if the user wants to be as anonymous as possible when surfing the web.
